The yellow color comes from bilirubin, a pigment in bile produced by red blood cells. Normally this pigment is excreted, but if too much bilirubin is produced or if the dog's body can't excrete it fast enough, there is an accumulation that results in jaundice. Many conditions can affect this process in dogs.

The tapetum lucidum is a reflective layer that causes the retina (the back of the eye) to appear green or yellow, or some color variation in between. This layer helps animals see better at night as it magnifies the amount of light and is most often noticed in animals that are nocturnal.

Grass turns yellow where dogs urinate because of chemistry. While nitrogen is an essential component of healthy soil, high concentrations of it can cause patches of grass to turn yellow or brown. Urine is naturally high in nitrogen, and nitrogen alone can cause grass burns. Lawn fertilizer also contains nitrogen.

Some noses fade during the colder months and return to their normal color during the summer months. This is a condition known as 'snow nose' or 'winter nose.'

Blue skin and mucus membranes, or cyanosis, is caused by a decrease in oxygen. This is usually a result of an underlying condition that affects the production and distribution of hemoglobin. This change in color of the mucus membranes is because of a lack of oxygen to the dog's blood caused by an underlying disorder.

according to AKC breed standards, Labradors can not have green or blue eyes. Their eye color should be brown to dark brown/black or yellowish. I cant say it impossible for this to happen but it would be fairly unlikely that 2 truly purebred labs would produce a blue-eyed pup.

Raccoons can actually have green, yellow or blue reflective eyes. The eyes of cats and dogs see best in the low light of twilight. They are classified as crepuscular rather than nocturnal, but both species are hunters who can see well enough to catch nocturnal prey.

Paper wasps and hornets, like yellow jackets, are social wasps (that is, they form colonies) but they nest aboveground. They also help control garden pests. Both can inflict nasty stings and can be aggressive, but they don't scavenge like yellow jackets and so are less likely to show up at outdoor activities.

Unlike cats, dogs do not have retractile claws. The color of the nail is determined by the color of the surrounding skin and hair.

It occurs most commonly where tears moisten the fur around the dog's eyes or around their mouth where saliva wets their fur as well as where they lick their feet and forelegs.

Darkening of skin in dog due to mange. Another possibility for dark skin on a dog's belly is the presence of parasites, in particular, sarcoptes scabiei mites, which are known to cause in dogs sarcoptic mange. The mites cause dogs to be very itchy and the blackened skin may be sparse around the body.

Nuclear sclerosis. Nuclear sclerosis, also called lenticular sclerosis, can cause the pupils of your dog's eyes to take on a cloudy bluish-gray appearance.
